CLEMENT CONCRETE DRAINTELE MACHINE 15 Sheets-Sheet 3 Filed NOV. 6, 1953 IN VEN TOR. @mn fs a,m mr United States Patent CONCRETE DRAIN TILE `MACHINE Charles D.Clement, Cornelia, Ga. p Application November-6, 1953, Serial No.390,521 l 1 Claim.. (Cl. 25 36) This invention relates to machines ordevices for the production of concrete drain tiles.

The principal object r4of the present invention Iis Ato provide amachine whereby/concrete drain tiles -are manufactured `from a semi-dryconcrete mix in a quick and etlicient manner.

Another important object of the invention Iis to lprovide a simplifiedand low cost machine for the manufacture of concrete drain tiles whichbecause of its lowcost can lbe found well within the reach -of mostlandowners and others requiring considerable drain tiling. i

Still another important object of theinvention isy to provide a machine`of the character stated which is positive acting and substantiallyfoolproof in-operation at all times.

A further lobject ofthe invention is to provide a machine which isVdurable and `not susceptible to the ready `development of defects.

These and various other important objects and advantages ofthe inventionwill become apparent tothe .reader of the following description.

There is a powerdriven pulley 25 fonthis spindle, above the bearing 22, as seen in Figure 7. An internalcombustion engine of low horse power can be utilized yin operating themachine through the medium of a belt (not shown) uto the pulley 25.

i From the end portions of the inverted channeled member21-, risetubular posts 26, 26 and on these lposts 26 -ri'de Ysleeves 27, 27.

Referring to Figure 8, it can be seen that numeral 28 generally refersto a mold band, which is a metallic band 29,:split longitudinally as at30, so that it can be slightly lopened by means hereinafter described inorder to permit `displacement of a formed or molded drain tile 31. (SeeFigure 10.)

Numeral 32 denotes an annular shoulder having a slop- *ing yIside wall,YJfor receiving the llower end of the band 29, as shown in Figure 8 andtubular struts 33, 33 extend from this shoulder 32 and connect at theirouter ends 'tothe lower portions of the Vsleeves 27, 27. It will beobserved that where convenient thevarious connections are made byWelding.

The shoulder 32 has a depending apron 34, through which the packerhead24 is snugly slideable, this packer- I ice fhead being preferably hollowand of cylindrical shape,

fthe upper end of which having stud bolts 35 rising 'therejfrom toaccommodate adjustable packer elements. These packer elements Vare inthe form of cam-like shoes `36, 36, veach of which has a leg 37, 'theselegs being disposed vvunder a `strap 38 having downturned end portionsand v with' nuts 39, 35

Figure 18 is a fragmentary bottom plan view of the hopper.

Referring to the drawings wherein like numerals designate like parts, itcan be seen that the machine includes a base which may be formed of apair of elongated supporting members 20, 20, bridged by a channeledmember eachstrap is formed with an opening to'receive a correspondingstud :bolt 35. These stud bolts are equipped 'which when vtightened downon the straps V38 will hold the legs 37 firmly in place and the packershoes 3'6 ina definite adjusted position. This adjustment allows forwear on the shoes. A glance atFigure 11 will show the'disposition of thepacker shoes 36. These shoes serve to pack the concrete against theinside o'f the vband 29, asv the band and its 'concrete content lowersdownwardly on the .packerhead cylinder 24.

Tubular struts 40, 40'extend inwardly from the upper `endsof thes'lidesleeves 27, 27 and are welded or otherwise secured to the ends of a yoke41 having an inside diameter approximately the same as the outsidediameter of the mold band 29.

Numeral 42 denotes a concrete containing hopper having a bottom 43, sidewalls 44 and a back wall 45. A hinge connection 46 is provided betweenthe rear portion of bottom 43 and the yoke 41, as is shown in Figure 7.Thus the hopper becomes part :of the carriage and is 4capable of beingswung backwardly, out of the way when the mold band 28 is to be removed.

To maintain the carriage in elevated position, the upper end of one' ofthe posts 26 has an outstanding pin 47 and over this is engageable ahook 48 which is carried by one end .of a swingable arm 49 which ispivotally connected as at 50 to the adjacent sleeve 27 and the outer endof this arm 49 has a handle 51.

To maintain the hopper 42 downwardly upon the mold band 28, one side ofthe hopper 42 -is provided with a rockable lever 52. One end of thislever 52 is constructed to form a handle, while the opposite end isformed to provide a hook 53 which is engageable over one of the upperstruts 40, as shown in Figure 1. It will also be observed that the upperend of the mold band 28 abuts the bottom of the hopper 42, when thehopper is properly disposed thereover. v

Now referring again to the mold band 28, it can be seen that the upperend thereof ts within the yoke 41, as shown in Figure 8 and furthershown in Figure 4 and as is brought out in Figures 1, 2 and 18, thebottom 43 3 v of the hopper 42, at the forward portion of the concretepassing opening therein has a depending lip 54, which further serves asan abutment for the upper portion of the mold band 28.

At each side of the slit 30 in the mold band 28 is a cleat 55 and thesecleats are provided with ngers 56 which overlap the cleats as shown inFigure l0, when the band is closed. A pair of locks 57, 57 projectoutwardly from medial portions of the cleats 55 andhave handles 58protruding therefrom. A clip 59 is disposed over the locks 57 to holdthe same together and the mold band 29 closed. As is shown in Figure 8,the lower end of the mold band is provided with an in-turned ledge 60 toprevent the Vfresh tile from slipping outof ,the band when the band isremoved from the machine. I

In the use and operationof this machine, the hopper 42 is rst swungbackwardly out of the way of the upper end of the mold band 28, afterthe hook 53 has been swung olf of the strut 40. This removes the lip 54(see Figure 7) from in front of the mold band, so that the mold band canbe lifted from the shoulder 32 (see Figure 8) and swung forwardly fromembracement by the yolk 41. v s f `An emptied mold band 29 is placedin'anupright posivtion uponthe shoulder 32 andover the upper end of thepackerhead 24'. The hopper 42 is now swung to the position shown inFigure 7 and a semifdry concrete mix is poured into the hopper and intothe mold band 28 to the extent substantially shown in Figure 7.

The internal combustion engine (not shown) is now companion strut '40and the hopper 42 is swung backwardly clear from the upper end of themold band 28.

' This frees the lip 54 from in front of the band and the set inoperation or a4 clutch actuated so that the pulley wheel 25 is driven.The hook 48 is now released from the pin 47 (see Figure 3) and thispermits the carriage including the mold band 28 to move downwardly onthe packerhead 24 as the packerhead is rotated by the driven pulley 25and as the packer shoes 36 move against the concrete mix and force thesame against the inside of the mold band, as kthe mold band lowers onthe packerhead 24, the packerhead cylinder serving to form the openingthrough the tile as the tile wall is being formed by the packer shoes.

When the carriage has fully descended and the top of the `mold band 28has lowered to a point below the top of the packerhead 24, as shown inFigure 9.

The carriage is now lifted, and this moves mold band to the positionshown in Figure 8 with the freshly formed tile therein. The hook S3 isnow removed from the band with its tile content can then be removed fromthe shoulder 32. By removing the clip 59, and spreading the handles 58,58, the Vdrain tile 31 will easily slip from the band 29.

While the foregoing description sets forth the invention in specicterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to without departing from the spirit andscope of the invention as claimed hereinafter.

Having described the invention what is claimed as new In a concrete tileforming machine including a base, uprights on the base, a rotatablepackerhead on the base, an expandable mold band vertically slidable onthe packerhead, a carriage slidable upon the uprights, a yoke carried bysaid carriage and embracing a portion of said mold band, strutsinterconnecting said carriage and said yoke, a hopper hingedly connectedto said carriage and having an opening therein adapted to overlie thetop of said mold band, and a lip dependent from said hopper and abuttingthe mold band in opposed relation to said lyoke the provision of meansfor holding the carriage in Yelevated position, and lmeans for holdingthe hopper in .one of said uprights, a hook pivoted to said carriage andengageable over said pin.
